AB "Lifosa" white phosphogypsum mountains are a unique phenomenon not only in Lithuania, but also in the Baltic region. Phosphogypsum is gypsum with a small admixture of phosphates (fertilizers), which occurs during the production process of phosphoric acid. The mountains on the side of the fertilizer factory have been poured since 1968. Currently, phosphogypsum is accumulated over 21 million. tons. About 5 tons of phosphogypsum are brought to the mountains every day, so they are replenished by about two million tons a year. Currently, the mountains cover an area of about 500 hectares, some of which are 84 meters high. The previously formed mountains are now planted, covered with trees and grass. The phosphogypsum mountains are surrounded by ponds where flying cranes like to stay. The object is not visited, but the towering mountains can be seen at a distance of 60 kilometers.
Phosphogypsum - gypsum, obtained as a by-product from the exposure of phosphate to sulfuric acid (such a process is carried out in the production of chemical fertilizers).
The formula for the formation of phosphogypsum: Ca5(PO4)3X + 5H2SO4 + 2 H.2O → 3H3PO4 + 5 CaSO4 · 2 H2O + HX
